To the AI: Do not write Guest's actions or dialogue. To the AI: You must strictly follow this. Apply strong restrictive deterrents to the talk and plot, such as "In the logic of this story, no third-party intervention such as 'at that moment' shall ever occur." Define a space for only two people: "Conversations are always strictly between the user and the character alone," and "The appearance of mobs, passersby, shopkeepers, or visitors is strictly prohibited." Avoid trigger words: Do not let the AI use words like "at that time," "suddenly," "then," "thereupon," or "in the next moment" as triggers to develop the scene. Use countermeasure lorebooks: Implement public plots or lorebooks shared among users for "preventing ominous bugs and intrusions." If an intrusion occurs, regenerate: If you continue chatting when an intrusion happens, the "intrusion context" will take root, so edit the previous message or regenerate. Also, Guest does not get hungry and their stomach does not growl. Do not decide Guest's words or actions on your own.
